四、场景1需要接口地址
/admin/product/baseTrademark/getTrademarkList   获取全部品牌的数据
/admin/product/baseSaleAttrList  全部销售属性接口
/admin/product/spuImageList/{spuId} 获取某一个已有的SPU照片墙的数据
/admin/product/spuSaleAttrList/{spuId} 获取已有的SPU，已有的销售属性接口

{
  "category3Id": 0,
  "description": "string",
  "id": 0,
  "spuImageList": [
    {
      "id": 0,
      "imgName": "string",
      "imgUrl": "string",
      "spuId": 0
    }
  ],
  "spuName": "string",
  "spuSaleAttrList": [
    {
      "baseSaleAttrId": 0,
      "id": 0,
      "saleAttrName": "string",
      "spuId": 0,
      "spuSaleAttrValueList": [
        {
          "baseSaleAttrId": 0,
          "id": 0,
          "isChecked": "string",
          "saleAttrName": "string",
          "saleAttrValueName": "string",
          "spuId": 0
        }
      ]
    }
  ],
  "tmId": 0
}

六、研究添加与修改SPU接口?
/admin/product/updateSpuInfo   POST

{
   "category3Id": 0,//三级分类的ID
   "id": 0,//当前已有SPU的ID
    "spuName": "xxxx",//添加或者修改SPU的名字---将来带给服务器
    "tmId": '',//收集添加或者修改SPU品牌的ID
    "description": "",//收集新增或者修改SPU的描述
    "spuImageList": [ //收集照片墙的数据---数组
         {
          "id": 0,
          "imgName": "string",
          "imgUrl": "string",
          "spuId": 0
       }
  ],
  "spuSaleAttrList": [//收集销售属性与属性值携带给服务器
    {
      "baseSaleAttrId": 0,//收集新增|修改SPU销售属性的ID
      "saleAttrName": "string",//收集新增|修改SPU销售属性的名字
      "spuSaleAttrValueList": [
        {
          "baseSaleAttrId": 0,//销售属性值归属于那个属性
          "saleAttrValueName": "string",//销售属性值
        }
      ]
    }
  ],

}
{
    category3Id: 61,
    spuName:'一加',
    tmId:6,
    description:'一加属于中国品牌收集',
    spuImageList:[
        {imgName:'爱你呦',imgUrl:'http://www.xxx.com'},
        {imgName:'爱你呦1',imgUrl:'http://www.xxx.com'},
    ],
    spuSaleAttrList:[
        {
             baseSaleAttrId:1,
             name:'颜色',
             saleAttrValueList:[{ baseSaleAttrId:1,saleAttrValueName:'黑色'},{ baseSaleAttrId:1,saleAttrValueName:'黑色'}]
        }
    ]
}
